Out of 150 150 offspring born to a gray, short fin fish crossed to a long finned, blue fish heterozygous for both traits, how ma
1 answer:
Out of 150 offsprings born to a gray, 38 offsprings are expected to be blue with short fins
<h3>How to determine the expected number of blue fish with short fins</h3>To do this, we make use of the following representations
- L represents long finned fish
- l represents short finned fish
- g represents the gray fish
- b represents the blue fish
So, we have the following genotypes
Lg, Lb, lg, lb
In the above 4 genotypes, lb represent the blue fishes with short fins
So, the probability of selecting a blue fish with short fins is:
In 150 offsprings, we have:
n = 150
So, the expected value is:
This gives
Evaluate the product
Approximate
Hence, 38 offsprings are expected to be blue with short fins

The Greco-Persian Wars (also often called the Persian Wars) were a series of conflicts between the Achaemenid Empire and Greek city-states that started in 499 BC[i] and lasted until 449 BC. The collision between the fractious political world of the Greeks and the enormous empire of the Persians began when Cyrus the Great conquered the Greek-inhabited region of Ionia in 547 BC. Struggling to control the independent-minded cities of Ionia, the Persians appointed tyrants to rule each of them. This would prove to be the source of much trouble for the Greeks and Persians alike.
